How to service the knock sensor on 2001 Chevrolet Impala?

Users should begin the knock sensor servicing procedure by switching OFF ignition power while using proper automotive lift equipment. Unplug the wiring harness connector from the knock sensor before extracting the sensor from the engine block. The new knock sensor installation should omit thread sealant because factory pre-coating protects its threads thus additional sealant may decrease detection of detonation. Screw the knock sensor into its designated block position then achieve a torque value of 19 N.m (14 lb ft). Place the wiring harness in its connection to the knock sensor before lowering the vehicle.
